It is important to note that this lesson would fit best early in the Expressions and Equations unit of sixth grade. It is not intended for students to meet the full expectations of the grade-level standards addressed through only this selected lesson. Within the individual lesson, the selection of representations is purposeful and connects to the student’s familiarity with arrays. This lesson builds on grade 5 work of interpreting numerical expressions to describe calculations and transitions students to grade 6 work of viewing expressions as objects.

The format of this lesson has some interesting aspects to highlight. This engaging and active lesson is meant to spark conversation between teacher and students as well as students with one another. The teacher checks for understanding of algebraic notation and interpretation of visual models. This ensures that the students’ understanding of notation, properties of operations, and variables is sufficient to move forward.
